The superior parietal lobule of the macaque monkey occupies the postero-medial part of the parietal lobe and plays a crucial role in the integration of different sources of information (from visual, motor and somatosensory brain regions) for the purpose of high-level cognitive functions, as perception for action. This region encompasses the intraparietal sulcus and the parieto-occipital sulcus and includes also the precuneate cortex in the mesial surface of the hemisphere. It hosts several areas extensively studied in the macaque: PE, PEip, PEci anteriorly and PEc, MIP, PGm and V6A posteriorly. Recently studies based on functional MRI have suggested putative human homologue of some of the areas of the macaque superior parietal lobule. Here we review the anatomical subdivision, the cortico-cortical and thalamo-cortical connections of the macaque superior parietal lobule compared with their functional properties and the homology with human organization in physiological and lesioned situations. The knowledge of this part of the macaque brain could help in understanding pathological conditions that in humans affect the normal behaviour of arm-reaching actions and can inspire brain computer interfaces performing in more accurate ways the sensorimotor transformations needed to interact with the surrounding environment.
猕猴的上顶叶占据顶叶的后内侧部分，在整合不同来源的信息（来自视觉、运动和躯体感觉脑区）以实现高级认知功能方面发挥着关键作用，例如感知动作。该区域包含顶内沟和顶枕沟，还包括半球内侧面的楔前叶。它有几个在猕猴中广泛研究的区域：PE、PEip、PEci 前部和 PEc、MIP、PGm 和 V6A 后部。最近基于功能磁共振成像的研究表明，猕猴上顶叶的一些区域可能与人脑中的同源区域相对应。在这里，我们回顾了猕猴上顶叶的解剖细分、皮质-皮质和丘脑-皮质连接，以及它们的功能特性，以及与生理和损伤情况下人类组织的同源性。了解这部分猕猴大脑可以帮助我们理解在人类中影响手臂伸展行为正常的病理状况，并启发脑机接口以更精确的方式执行与周围环境交互所需的感觉运动转换。
